' SAND-REEL PEDESTAL AND CONTROL MECHANISM.

Application filed February 10, 1921. Serial No. 444,030.

To all whom it may concern:

7 Be it known that I, THOMAS W. HoLLnY, a citizen of the United States, residing at Ranger, in the county of Eastland and State of Texas, have invented certain new and useful Improvements in Sand-Reel Pedestals and Control Mechanism, of which the following is a specification. Y

My present invention relates to well drilling rigs and more particularly to pedestal andcontrol mechanism for the sand reels thereof used in the lowering and drawing of sand pumps or bailers. 7

It is now common practice to support the sand reel by a shaft received at one end by a tail post and at its other end by lever carried by knuckle post, the lever being manually actuated by a sand reel handle and reach connecting the handle and lever. The use of this arrangement results in notching or cutting of a gain in main sill for fastening of the knuckle post thereto materially weakening the sill. The lever,

usually made of wood receives the end of the sand reel shaft by a hole bored in the lever and which becomes rapidly enlarged making necessary replacement which takes time and is a considerable expense when replacement is frequently required. In the erection of welldrilling rigs it is the usual practice to frame the timber on the ground where erection is to take place and the erecrig,relating' to the sand reel takes considerable time and labor.

One of the principal objects of the present invention is to provide a pedestal and con trol for sand reels which may be quickly and securely placed and adjusted with respect to the main sill and usual band wheel of the rig to be operated thereby.

Another object of the invention is to provide a pedestal and control mechanism which is durable, the end of the sand reel being received in a bearing block adapted to receive a lining of alloy metal, such as Babbitt metal, readily replaced and capable of being remelted and reused.

A further object of the invention is to provide a pedestal which may be mounted upon and connected with the main sill of the rig without multilation of the latter.

Other objects and advantages of the invention will appear in the following detailed description taken in connection with the accompanying drawings, forming a part of this specification, in which drawings Figure l is aside elevation of a portion of well drilling rig showing a ped'estaland reel control mechanism, constructed according to theprinciple of my invention, applied thereto. V Fig. 2 isa plan view. of the sand reel por tion of the rig. T

Fig. 3 isa detail view partly in elevation and partly in vertical section of the pedestal and a portion of the control mechanism.

Fig. 4 is an enlarged'sectional. view" on the line 44' of Fig. 1 of the drawings.

In the drawings, where similar characters refer to similar parts throughout the views, A designates the main sill, B the sub sill, C the sand reel tail sill and D the mud sills of the rig; E the sand reel, F and G its shaft and pulleyrespectively; H the'b'an d tion is designated by L as to the pedestal and-M as to. control mechanism for the reel. tion and adjustment of this portion of the The invention is herein shown as applied to what is commonly known as the standard rig, in which the sand reel shaft F is disposed with -its axis extending diagonally cross wise the plane of band wheel'I-I, but

it is to be understoodthat the principle of this invention ma be applied to other types use of a cable 5, and this isaccomplished by moving the shaft F so that the pulley G is moved into and out of engagement with the band wheel H. I

The particular type of pedestal or tail post K, shown in Figure 2 of the drawings does not form apart of the present invention, but is more specifically disclosed in my copending application for patent ;hereinbefore referredto. It is sho'w'n'merelyby way of example to indicate that the shaft F, when moved, for bringing the pulley G into and out of engagement with the, band wheel H, pivots in bearing 6 of the pod estal K.

The pedestal L paises. b pilt ilyb bas 7, a frame 8, and a bearing block 9 slidable in frame 8. The base 7 has means 10 for securing the base to the main sill A of the rig, so that it may be adjusted longitudinally of the sill, or in other words, in a plane parallel to the plane of band wheel H. The frame 8 has'means ll'for securing it to the base 7' and permitting adjustment .of' the frame toward or from the plane of the-band wheel H.

' The base 7 in the example shown con prises a pair of base bars 12' arrangedin parallel spaced apart relation, and a connection 13, such as a piece of timber which is secured to. the under side of the bars 12, and which may be secured to the bars in any suitable mannensuchas by bolts'l l and nuts 15. The base bars '12 are preferably formed of rolled angle section, thus providing a horizontally disposed flange 16, and vertically disposed flanges 17. For a purpose to be subsequently set forth there is provided adjacent each end of flange 16), a perforation 18, and the vertical flanges 17 are each provided with a series of perforations 19 arranged longitudinally ofthe flange. The base 7 may also comprise one or morefiller pieces 2!), whichmay' be: interposed between the connection 13. and the base sill A, in order to dispose the base bars 12 at the desired distance above the upper face of the main sill, these filler pieces being preferably arranged directly beneath the base bars,

clearly shown'in Figure 1 offthe drawl gs- The means 10 for securing the base to the main sill may comprise clamp bars 21 adapted to engage the under side of sill A, and take up devices 22, which latter may each be in the form of a'rod 23 screw threaded at opposite end portions, and nuts 2% in screw threaded engagement with these end portions. Each clamp bar is provided adjacent its end portions withperforations 25, there being one clamp bar for each base bar, the perforations 25 being aligned with the perforations 18 in the base'bar. The rods 23 are thus accommodated in the perforations 18 and 25, and by turning the nuts-2a tiglit, the base 7 may be secured to the base 'si'll against longitudinal and'lateral movement with respect thereto. The base may be ad justed, however, longitudinally of'the sill, as is obvious from the foregoing, it being necessary to merely release some of the nuts 24: and shift the base 7 longitudinally of the sill.

The frame 8, in the, example shown comprises a pair of uprights 26, in spaced apart secured to the uprights 26 in spaced apart relation. The uprights 26 may be conveniently formed from rolled channel sections, one of which is provided with a vertical slot or ppeningfitl for a purpose to be subsequently set forth. The guide members 27 maybesubstantially':H'shaped in cross section, whereby each member is provided with parallel flanges 29, serving to hold the bearing block 9 against movement laterally of the frame. The guide members maybe secured to the uprights, in any suitable manner, such vas by boltsand nuts 30 and 31, respectively.

Referring now tothe means 11 for securing the frame -8-to the base 7, permitting adjustment of the frame toward or fromv the plane ,of the band wheel'l-I, such may consist merely of bolts 52' and nuts 33, although it is desirable, to also provide braces ea, connected-to the upper portion- "of the framea s by one of the bolts "30 and nuts h and to the base bars as by bolt 34; and nut 35, these braces acting as struts, since most o-f -the pressure incidentto operation of the sand reel, is outwardly, the bearing 'blocktl acting somewhat as a thrust bearing where a bev eled pulley G is used. The shanks ofbolts 32 may be extended through -anyselected perforations 1'9, these-perforations permita ting of adjustment-of the frame8 towardeor from the plane ofthe band wheel 1H.

Bearing block 9 may beformed of a sin.-

gle piece of metal, or maybe built up in any suitable manner, it sufficing to show,

in the example shown, that the block is provided with an opening 36 for the reception of shaft F, alining {of Babbitt metal or its equivalent 37, being provided in said open-- ing, and the bloclnalso having grooves 38 at its upper andlower-facesfor the reception of the flanges, 29. While but slight movement of the block is necessaryto bring the pulley G into and out of engagement with the band wheelH, theframe 8 isrnade relativelylong so that it is possible to move the bearing block '9 a considerable distance in either direction, before 'it will engage either uprights 26. This has a material'advantage as will be noted hereinafter, since it is not always possibleto clamp the base 7' to the main sill in a manner that the shaft E is accurately positioned for engagement of the, pulley with the band wheel H, by operation of the mechanism The mechanism M comprises, an arm 40 extending from one, end of frame 8-; a lever 4-1 in the example shown, pendently supported by arm '40; a link 4 2 connecting bearing block 9 and lever e1; anarm 43 extending from base 7 in the same direction as arm 40; a lever d4; pivotal ly cornected to arm d3 at one. end and to [lever a l intermediate its ends; a sand reellever relation, and horizontal guide members 27 as on platform J adapted towbe manually actuated; and a reach 46 operatively connesting levers 44 and 45, so that when movement is imparted to lever 45 it will be transmitted through reach 46, lever 44, lever 41 and link 42, to the bearing block 9. It is preferred to provide the arm 40 with a p1urality of perforations 47 longitudinally thereof, and to provide a plurality of perforations 48 in spaced apart relationlongitudinally of lever 41. Also link 42, may be provided with a plurality of perforations 49, so that the connecting device 50, such as a bolt, which pivotally connects the lever 41 to arm 40 may be disposed in any of the perforations 47 and 48 selected, for adjust ment. Likewise connecting device 51 for the link 42 and lever 41 may be passed through any of the selected perforations 48 and 49, for adjusting purposes, as hereinafter noted. The arm 43 and lever 44 is provided mainly to permit of disposing the sand reel operating lever 45 in the belt house or well within the margins of the platform J, and so as to avoid engagement of the reach 46 with a standard 52 of the band wheel H, which is usually a stock feature. The connection between lever 44 and arm 43 may be by means of a pin or bolt 53 extending through an elongated slot 54 in the end portion of lever 44. The reach 46 may be made up of a plurality of sections detachably and adjustably connected, as indicated at 55, and the end portion of the reach adjacent lever 45 may be provided with a plurality of perforations 56 any one of which may be aligned with any one of a plurality of perforations 57 in lever 45, a bolt 58 serving to pivotally connect the lever with the reach. a

It is to be noted that the perforations 47, 48 and 49 permit a wide range of ad- 'ustment as to the relative osition between 3 the bearing block 9 and the operating lever 45. The relatively long guide bars 27 enable the workmen to quickly assemble the pedestal into operative relation to the main sill by use of means 10, accurate adjustment at such time not being necessary. WV hen assembling the shaft into operative relation with the bearing block 9,

the entire frame 8 may be moved toward or from the complemental pedestal K, according to the length of the shaft to be accommodated, this being possible because of the provision of means 11. After the mechanism has thus been assembled it is desirable to adjust the mechanism so that the pulley G will have good frictional contact with the band wheel I-I, so as to not wear the latter. This may be accomplished by either adjusting thepedestal K, or by adjustment of the mechanism M. The link 42 extends through the opening 28 in upright 26, which opening is of suflicient size combination, a pair of base bars arranged in parallel spaced apart relation and each having a longitudinally and a vertically disposed flange,'said horizontal flanges provided with perforations adjacent their ends and said vertical flanges each provided with a a series of perforations arranged longitudinall of the flange, a clamp bar for each base ar, said clamp bars provided wit-h perforations aligned with said perforations in the horizontal flanges of said base bars, adjustable take up devices accommodated in the said aligned perforations of said clamp bars and base bars for clamping the base bars to the main sill of the rig, a bearing block, a frame receiving and guiding said bearing v block and permitting movement thereof longitudinally of the frame, and means securing said frame to said base bars in adjusted position longitudinally thereof, said means including elements passing through selected'perforations in said vertical flanges of said base bars.
